Tiffany custom-made the neckpiece to match Lady Gaga’s bluey-lilac Valentino Couture gown, one of the most acclaimed — and photographed — fashion items from the ceremony. The star’s association with the New York luxury retailer dates back to her appearance in its debut Super Bowl commercial in February 2017.

“The Tiffany Aurora necklace, specially crafted for Lady Gaga and today’s Globes, captures the majestic nature of her dress perfectly,” said Sandra Amador and Tom Eerebout, the Golden Globe nominee’s stylists. “What could be more fitting than this exquisite custom piece, named after the goddess of dawn, and a cluster of stars, to mark Lady Gaga’s wonderful work in A Star is Born?”

Sandra Oh, who hosted the awards and won an accolade for best actress in a television drama, wore a mixture of Forevermark rings, earrings, bracelets and bangles. She sported three different looks for the red carpet, her opening monologue and when she accepted the award.

“Forevermark diamonds were not only perfect but felt perfect for the message: Sandra Oh is a rare, beautiful, smart, talented person,” said her stylist, Elizabeth Saltzman, referring to the De Beers-owned jeweler’s focus in its branding on empowered female consumers who buy diamonds for themselves. Forevermark’s marketing has targeted that demographic in recent years in response to an increase in self-purchasing by women.

Gemma Chan, who appeared in the Golden Globe-nominated movieCrazy Rich Asians, also wore Forevermark jewelry, including a cushion-cut, 11.03-carat diamond ring set in platinum. Actress Allison Janney, who won a Golden Globe in 2018, wore Le Vian ruby and diamond earrings.
